<hr><a name="_details"></a><h2>Detailed Description</h2>
An AtkImage C++ wrapper class. 
<p>
<a class="el" href="classGFC_1_1Atk_1_1Image.html">Image</a> should be implemented by <a class="el" href="classGFC_1_1Atk_1_1Object.html">Atk::Object</a> subtypes on behalf of components which display image or pixmap information on-screen, and which provide information (other than just widget borders, etc.) via that image content. For instance, icons, buttons with icons, toolbar elements, and image viewing panes typically should implement <a class="el" href="classGFC_1_1Atk_1_1Image.html">Image</a>.<p>
<a class="el" href="classGFC_1_1Atk_1_1Image.html">Image</a> primarily provides two types of information: coordinate information (useful for screen review mode of screen readers, and for use by on-screen magnifiers), and descriptive information. The descriptive information is provided for alternative, text-only presentation of the most significant information present in the image.
